Description
<SDU error ratio> a string parameter that indicates the target value for the fraction of
SDUs lost or detected as erroneous. SDU error ratio is defined only for conforming
traffic. The value is specified as ‘mEe’. As an example
a target SDU error ratio of 5•10-3 would be specified as ‘5E3’ (e.g.
AT+CGEQREQ=…,”5E3”,…). ‘0E0’ means subscribed value (refer 3GPP TS 24.008
subclause 10.5.6.5).
<Residual bit error ratio> a string parameter that indicates the target value for the
undetected bit error ratio in the delivered SDUs. If no error detection is requested,
Residual bit error ratio indicates the bit error ratio in the delivered SDUs. The value is
specified as ‘mEe’. As an example a target residual bit error ratio of 5•10-3 would be
specified as ‘5E3’ (e.g. AT+CGEQREQ=…,”5E3”,…). ‘0E0’ means subscribed value
(refer 3GPP TS 24.008 subclause 10.5.6.5).
<Delivery of erroneous SDUs> a numeric parameter that indicates whether SDUs
detected as erroneous shall be delivered or not.
0 no
1 yes
2 no-detect
3 subscribed value
Other values are reserved.
<Transfer delay> a numeric parameter (0,1,2,…) that indicates the targeted time
between request to transfer an SDU at one SAP to its delivery at the other SAP, in
milliseconds. If the parameter is set to ‘0’ the subscribed value will be requested (refer
3GPP TS 24.008 subclause 10.5.6.5).
<Traffic handling priority> a numeric parameter (1,2,3,…) that specifies the relative
importance for handling of all SDUs belonging to the UMTS bearer compared to the
SDUs of other bearers. If the parameter is set to ‘0’ the subscribed value will be
requested (refer 3GPP TS 24.008 subclause 10.5.6.5).
<Source Statistics Descriptor> Supported in R7 P S a numeric parameter that
specifies characteristics of the source of the submitted SDUs for a PDP context. This
parameter should be provided if the Traffic class is
specified as conversational or streaming (refer 3GPP TS 24.008 subclause 10.5.6.5).
0 Characteristics of SDUs is unknown (default value)
1 Characteristics of SDUs corresponds to a speech source
